19 (AZ! to 710m it may concern:

Be it known that l, PAUL S. BARBAY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful linprovei'nents in Locks, of which the following is a specification.

This invention relates to a door look.

It is the principal object of the present invention to provide a combined key and knob operated door lock equipped with means whereby the lock may be rendered ineffective for operation by either the lrey or the l-znob when desired, or 'llf/ be operated by the key alone as controlled by release aneans on the inside of the door, all of which construction is COlIlPRt-i? in its arrangement and direct in operation.

The present invention contemplates the use of a .ool: structure adapted to be mounted against the inner face of a door and be equipped with single bolt, which may be actuated by rotation of knobs on the op the door after operation of a key mechanism airessible to the front of the door, structure being further fitted with release means on the insideof the door rendering the knob and key mechanisms in operative when desired.

he invention is illustrated. b war of example in the accompanying drawings, in

which:

Referring more particularly to the drawings 20 indicates a case, within which a lock structure is housed. This case is adapted to lie flush along one of the side faces of a door and in position over a back plate 21, which is preferably secured direct to the door. A lock barrel opening 22 is formed through the door at a point in the rear of the case and is in communication with a bolt passage way 23, extending at right angles thereto, and terminating in the edge of the door. At a point higher up in the door a knob opening is provided. Thus it is only necessary to bore two holes through the door and one hole in the edge thereof. A liiarrel lock 2 is suitably mounted within the opening 23, while a lock bolt 25 is positioned within bar case 26 disposed within opening A knob shaft 27 extends through the knob opening in the door and receives knobs 28 at the opposite ends thereof.

In the form of the invention shown in l to 9, inclusive it is intended that perspective showing loch mechanism with of the device shown perspective showing the opening 23 the operation of the knobs shall actuate the bolt and that this action shall be controlled by the movement of a key within the lock 24-. or rotation of a safety knob 29 on the face of the case 20 which is disposed within the room. This is brought about by the assembled mechanism particularly disclosed in Figs. 1 and 2, where it will be seen that a knob actuated arm 30 is secured upon the squared knob shaft 27, and is fitted with a lift finger 31 pivoted upon a pin 32 at its outer end. The upper end of the finger 31 is formed with a squared face 38 adapted to be borne against by a spring finger 34. Due to the angular position of the face 38 relative to the general position of the finger the spring lever will normally act to throw the catch portion of the finger out of engagement with a lug 36 of a draw rod 37. An expanding spring 38 constantly acts on the spring lever 3 1 to force it downwardly and into continued contact with the face 8-3 of linger 31. Reciprocal movement of the finger 31 is brought about by oscillation of the knob actuated arm 30, this movement at the same time being accompanied by a slight swinging movement of the finger around its pivot 32 as the finger is drawn along face 38 of a wedge member 39.

The draw bar 37 is pivotally connected at its lower end with a lever arm 40. This arm is formed with a circular boss 41 extending through an opening d2 in the back plate 21, and being further provided with a squared portion resting in a sim'lar formed seat 4:8 of a bolt lever 4:4. This lever is disposed within the opening 22 of the door and when swung in a direction away from will engage a stop 45 as shown in F'g. 12 to retract the bolt 25. The stop 15 is formed on an extension plate 26 of the bolt as more clearly shown in Figs. 8 and 12. Adjustment of the bolt is provided by an interposed threaded shaft 17, to which the plate 46 is secured and which in turn is threaded into the end of the bolt. Lock nuts 4-9 are provided to set the members in their adjusted positions. The bolt case 26 is suitably formedto receive'an expansion spring 50, which will act to force the bolt in its outermost position at all times. Due to this arrangement rotation of the door knob with the resultant lifting movement of the lever will normally art to the catch of finger 31 to engage the lug 36 of draw bar 3'7 and swing the lever 4.0 upwardly, at the same time swinging bolt lever 44: rearwardly and retracting the bolt 25. A spring 51 is used to normally swing the draw bar in a position' to be engaged by the fingers 31.

The bolt actuating means as controlled by the knob, may be rendered inoperative by both the key lock 24hr the movement of the safety knob 29. The former mechanism compr ses a trip member 52 which is in the shape of a short arm disposed in a plane parallel to the arm 10 connected with the draw ba 37. This trip member is fitted with a stem 53 extending down through the bolt-cam 14i. forinei'l with a squared projection 54-, which extends into a slot 55 made in the rotatable v art of the barrel lock mechanism. The trip member is provided with an inwardly projecting lug 57, which is of substantially the thickness of the arm l0, which it overhangs. The end this lug is relieved for a purpos '"hlch will hereinafter be described. otation of the trip member 52 is independent of rotation of the arm 40 is intended to actuate a lock cam 58. ns cam is mounted for free rotation upon a pin 59, to which the safety knob 29 is r dly secured. This lock cam is provided in h an extending lug 60, which may be encountered by the trip member 52 as it swings in the direction of the arrow a-, as indicated in Fig. 2. The opposite side of the trip member is formed with a series of gear teeth in mesh with the gear segment 62. This segment forms a part of a release finger 63, which may swing in the direction of the arrow b and force the draw bar 37 to an inoperative position. A V-shaped catch recess 64 is formed in the edge of the trip member 52, and may be engaged by the hook end of a catch arm 65, which may swing upon its pivot 66 as influenced by a spring 67. Eleturn movement of the member 63-ls limited by a stop pin 68, while the extreme outward movement of the draw bar 37 is limited by a stop pin 69.

The safety lrnob 29 renders the knob mechanism inoperative by means of a release pawl 70 secured thereto and adapted to rotate therewith. This pawl has an extension 71 at one side of its axis, which is intended to swing out against a leaf spring secured to the side face of the draw bar and to thereafter force this spring flat and continue to swing until. the draw bar has been moved in the direction of the arrow 6 to the position indicated inFig. 2. The opposite side of the release pawl is formed w th an arcuate face 7 2 engaging the point of the catch and swinging it out of its locked position relative to the recess 64. An extending arcuate portion 73 adjoins the other face and in the extreme locking position of the pawl rests directly against the catch portion of the member 65, tending to more rigidly secure the pawl in its locked position.

Reference being had to Fig. 10, a modification of ti e invention is shown in which the release pawl is eliminated and a safety lever 74 is used in its place. This lever is rigidly secured to the end of the pin 59 and may be swung around to engage the The end of this stem is 1 ,asapeo extension of the lock cam 58 or to strike the catch member and swing it to a release position. All of the remaining mechanism is identical with that previously described.

In order to make the invention simple in its application, the barrel lock 24 maybe readily secured in position in the manner shown in Figs. 13 and 14. This is done by providing extension fingers 75 at the end of the barrel, which fingers have serrated outer faces 76 at their ends. A wedge washer 77 is driven into the opening 22 and between the fingers 76, forcing them outwardly into the wood of the door, and rigidly securing the lock barrel in position.

In operation the lock is normally in a position so that the bolt 25 may be reciprocated by rotation of either knob. This normal position is clearly indicated in Fig. l, where it will be seen that upward swinging movement 30 in the direction of the arrow cZ will lift the finger 31, causing its catch to engage the lug 36 of bar 37 and draw this bar upwardly in the direction of the arrow e-. Upward movement of the arm l0 will then be produced, which movement will be imparted to the bolt cam 44, and this cam in turn will retract the bolt. If the door is to be locked by a key a rotation of the key will cause the member 56 of the lock barrel to be rotated. This will turn the stem 53 of the trip member 52 and will swing this member in the direction of the arrow a, causing the lock cam 58 to rotate in an opposite direction around the pin 59. The engagement of the cam with member 63 will cause this member to swing outwardly, thus disposing the projection 60 of the lock cam and the member63 against the side of the draw bar, to forcibly hold the draw bar in an inoperative position as wedged between these two members and the pin 69. The draw bar will be held in this position due to the ment of the catch 65 with the recess 64: of the lock cam. This action may be discon: tinued, however, by movement of the safety knob and rotation of the release pawl 70. Rotation of this pawl in the direction of the arrow f will cause the end 71 to strike the bar and hold the same in its locked posttion, but at the same time will swing the catch 65 out of engagement so that a return of the pawl will release the draw bar and permit it to move to its position for engage ment with the finger 31. As previousy stated the action of the mechanism 10 will be substantially the same as this with the exception that the member 74 will take the place of the member to cause indirect locking of the draw bar by the members 60 and 63.

It will thus be seen that the lock here dis closed is quite compact in its design and arrangement, may be easily installed and readily operated to become locked from either engageside of the door and to be rendered entirely inoperative by manipulation from the inside of the door.

While I have shown the preferred form of my invention, as now known to me, it will be understood that various changes might be made in the combination, construction, and arrangement of parts, without departing from the spirit of the invention, as claimed. 75
